At the time of the 2009 American 738 overrun in Kingston, Jamaica, it was pointed out on this forum (not by me) that the geometry of the "stretchiest" 738/9s - the angle between the gear and tail - meant less leeway for avoiding tailstrikes, and thus perhaps a tendency to land with less AoA/pitch and higher speed.
The A320 family have taller landing gear and thus a slightly more generous tail clearance.

However, I'm in total agreement with the previous posts - unless one filters and cross-references overrun events for a
host of other factors: runway length, runway slope, weight, weather, fleet size, crew training, operator quality, specific aircraft subtype, etc. etc. - that is a difference that may not really
make a difference.
The Kingston event involved not just a wet runway and a 738, but also a tailwind barely within limits and a late touchdown (4000 feet/1200 meters/halfway down the runway).
